Each of the paris 39 and 40 are provided with an end flange such as 41 and 42 and the end fianges are adapted to abut one .another for attaining proper positioning thereof relative one another and for effecting a supporting strut for and beneath the center of The grooves or channels 43 and 44, formed along the portions of the pans 39 and 410 and opposed to the portions thereof carrying the depending fianges 41 and 42, function in the same manner as do the channels 22 and 23 formed along the spaeer 13 illustrated in IThe hanger inserts 45 may be positioned between the fianges 41 and 42, as illustrated in l'ig. 4, or suitable apertures', corresponding to the apertures 36 shown in spacer 13, may be provided for Cooperation with the hangers 45. Likewise, apertures such as 28 in spacer 13, may

v be provided in the spacers 39 and 40 for temporary fixation of the same to the temporary centering.

After the concrete slabs and 4.6 and 12 respectively have been formed and the plastic has set suficiently to permit removal of the centering and shoring 11 and lb respectively, metal lath 33 may be Secured to the under surface of the resultant floor Structure, means of the hange inserts such as 800. By reference to Figs. 1 and 4, it will be obvious that a space is provided above all of the la'th 33 wherefore the plaster 47 is applied over a uniform surface. It will also be noted that the depth of the pans .or space' members, such as 18, determine the spacing of the plaster from the lower edge or base of the concrete ribs 36, wherefore, by modifying the depth of the spacers 13, variablespacingof the plaster ceiiing from the ribs 36 may be attained.

-Although the invention has been disclosed' herein in terms of sheet metal, spacer members 13 and arched forms le and metal lath, it is to be understood that the invention is not limited to elements of the Specific materials indieated. It is also to be understood that the invention is not limited to structures wherein metal lath isl aifixed after the temporary center-ing and shoring is removed, it being obvious that the metal lath maybe applied over the temporary centering or flooring,'and that the space: memlers A`13 and arched forms Ie may be erected over the metal lath and that suitable tie means, such as inserts 300, may be ernployed for retaining the lath in position, so that after .removal of the temporary oentering 11 and sharing io, no further work, in

connection with attachment of' the lath to the resultant Structure, need be resorted to.

In some instances it may be desirable to fabricate spacer members 13 of material sufiiciently substantial or heavy to permit elimination of the temporary centering, the members 13 being supportedffrom the steel frame work of the build-l fore it is to be understood that the terms tile or arched form used herein, comprehend such other tion, the combination of temporary support means, rows of eiongatedhoilow inverted U-.

shaped members on the support means, the rows of members being contiguous along their later-al edges, the lateral edges of alternate rows of the members having pockets, the intermediate rows of members having their lateral edges received Y in the pookets the rows of inverted members spacing concrete formed thereover, from the temporary support means, and together providing abutment means along the under faces thereof and against which abutment faces lath may be Secured in spaced relation to the ooncrete.

2. In a concrete fioor in course of construction, the combination of temporary fiooring, roWs of laterally contiguous inverted U shape members, the rows of U shape members being longitudinally cotermnous and of different heights for providing beam. molds between the adjacentL higher members, and insert members having a portion disposed in the beam molds for bonding with the concrete to. be formed in the beam molds, and having a tying portion extending through the shallower U shape members for securin'g lath against the under edges of the U shape members in spaced relation to concrete form'ed over the Lbshape members. f

3. In a concrete fioor in the course of construction, the combination of parallel rows of hollow spacer members, rows of tiles between the spacer members andl comprising depending walls hav" spacer means for securing the spacer members toV the concrete and for securing lath against the lower edges of the spacer members and tiles and in spaced relation below the ribs formed in the rib'rnolds. i

4. In a concrete floor in the course of oonstrm-` tion, the combination of parallel row's of hollow spacer members, the spacer members coinpris ing key forming parts between whichconcrete or thelike may be received, rows of tilesbetween the spaoer members and comprising depending walls having their lower edges interengagedwith the spacer members along the lateral edges of the spacer members, the tiles and spacer means providing a continuous surface for defining spaced rib molds over the spacer members and between thetiles, lath beneath the tiles and spacer members, and means extending above and below the spacer means for securing the spacer rnembers to the concrete and for securing lath against the lower edges of the spac'er members and tiles and in spaced relation below the ribs formed in the i rib molds.
